pydev debugger: CRITICAL WARNING: This version of python seems to be incorrectly compiled (internal generated filenames are not absolute) [duplicate]

Question

By running:

from sklearn.datasets import fetch_california_housing
import pandas as pd

pd.set_option("precision", 4)  # massimo numero di cifre decimali
pd.set_option("max_columns", 9)  # massimo numero di colonne da visualizzare
pd.set_option("display.width", None)  # larghezza caratteri sul prompt dei comandi

housing = fetch_california_housing()  # carico il dataset (http://lib.stat.cmu.edu/datasets/)
print(housing.DESCR)

i receive an alert and an error:

I have installed Python 3.11.0 using Pyenv on Mac OS X 12.6.1, with PyCharm 2022.2.3 by setting the interpreter.

Previously i was using Python 3.10 by a simple installation, but yesterday i have installed Python 3.11 using pyenv because i was having a problem in importing a dataset from sklearn.

I checked the frameworks.python folder and this is the output

Answer 1

I had a similar problem; updating PyCharm to 2022.3 fixed the issue for me.

Answer 2

This is an issue with the bundled version of pydev.debugger.

You can fix it by adding -Xfrozen_modules=off in the "Interpreter options:" field of the Run/Debug window.
